Shimano BR-M454, needs new brake pads/shoes
I'm prepping a 90 Trek 7000 I bought 3 years ago, to begin riding again. Tires, tubes, brake pans and cables are all original to the bike. I doubt it was ridden more than a couple hundred miles. Tires are dry rotted in the gum sidewalls, so replacing them, cables all seem to be smooth, shifts well.So looking for the best replacement shoes/pads. I'm a heavy guy, but losing it pretty good right now, feeling like I need to get on a bike again to keep going lower.

Reviving my own thread, so not really a Zombie effort...
1990 Trek 7000. Original Shimano BR-M454 calipers. Original Matrix "Aero" wheelset. Aero, meaning narrow. Essentially they are the same as the road rims of the era, just 26" MTB not 700c. Original brake pads were hard and cracked. I had a tough time finding threaded replacements. I would up using threaded V brake pads, but they are lower cross section than the original pads, and getting them lined up on the rims is not working, they don't sit flat on the braking surface.
I keep the bike at work, it is rural and I don't ride it much, but it is nice to have when I want to. But, I want to swap it for a different bike and I want it to stop better.
Which brings this old topic back from the dead.
I was reading this thread on CX50 brakes today... And that got me thinking these might be the replacement I need.
Replacement pads and standoffs for the BR CX50 cantilevers. Which aren't cheap, but not terrible either. And at least, pretty similar to what I took off the bike.
Or, as mentioned in the above referenced thread, using road bike pads in place of the CX50 pads. I'm also NOT ruling out Kool Stop pads, but they don't offer a pad that a bolt threads into, just a threaded stud from the pads.
I want to keep the 7000 as close to original as possible , so I won't swap the calipers out. The BR-M454 calipers seem to have been produced 1989 to 1991, so even NOS would be hard to find and hard as rocks.
Am I on the right path here?

Having suffered through abysmal stopping ability of Shimano pads (even though they indeed looked cool), I cannot recommend them over KoolStops, which will actually stop your bike on a downhill slope under moist or damp conditions.

Kool stop crosspads are solid. Kool Stop International - High Performance Bicycle Brake Pads Since 1977 They also have non-cartidge versions that are cheaper. https://www.koolstop.com/images/ks-sup2dl_art_lg.jpg
